인터넷의 보급 확산과 정보통신기술 및 웹 기술의 발달로 쇼핑몰 사이트가 등장하게 되었다. 현재 쇼핑몰 사이트는 그 종류가 다양해지고, 규모가 대형화되고 있으며, 매출규모 또한 증가하고 있는 추세이다. 이러한 많은 쇼핑몰 사이트들은 매출경쟁에서 자사의 수익창출을 위해 끈임없이 노력하고 있고 특히, 고객이 편리하게 쇼핑을 할 수 있도록 원활한 페이지 이동을 지원하고 있다. 고객의 쇼핑과정에 영향을 미치는 페이지 이동을 기존의 웹사이트 설계기법인 플로우차트, 스토리보드, 사이트 맵으로 표현하기에는 미흡한 점이 있다. 따라서 본 논문에서는 개념적이고 직관적인 설계가 가능한 EMFG(Extended Mark Flow Graph)[6]를 이용하여 쇼핑몰 사이트에서 웹 페이지간의 이동흐름을 나타내는 링크구조를 표현하고 분석 한다.

It is very useful because we can measure precise exercise volume at indoor and outdoor space, and receive push message and retrieve for exercise information by smart-phone at any-time and any-place if a fitness healthcare system base on IoT is utilized. This system is interlocked with IoT module including sensing device in sports equipment, IoT gateway, smart-phone, smart-band and server by internet. In this paper, when this, "a fitness healthcare system base on IoT", software is developed, a proper analysis and design method for practical affairs try to be presented due to showing software development analysis method and design method such as flowchart and UI design.

Although the round length for tunnel excavation has a major technical and economical impact in conventional tunnelling, there is no coherent procedure available for its determination. In this study, the influence of round length on the behaviour modes of weak rock tunnel was investigated by numerical analyses. Quantitative estimation of the behaviour modes of the face and the unsupported span was established by use of the safety factor for the face stability and the conditional chart. In addition, the optimum round length in the tunnel design stage was investigated based on the detail construction information such as cycle time and material costs. Although this proposed method has some restrictions, it is expected to provide useful information for the optimization of the tunnel excavation, especially in design stage.

A core technology of social robot is voice recognition and dialogue engine technology, but too much money is needed for development and an implementation of robot's conversation function is difficult resulting from insufficiency of performance. Dialogue function's implementation between human and robot can be possible due to advance of cloud AI technology and several company's supply of their open API. In this paper, current intelligent social robot technology trend is investigated and effective social robot system architecture is designed. Also an effective analysis and design method of social robot system will be presented by showing user requirement analysis using object-oriented method, flowchart and screen design.

A rigorous field analysis by the non-decaying mode and the contour graph method is presented for dielectric-rod loaded cylindrical cavity resonators. Resonant frequencies and the lowest order modes for this resonator are calculated. The mode charts are presented to design the resonators. TE mode(transverse electric or H mode, having no Ez), TM mode(transverse magnetic or I mode, having no ㎐) and HEM mode(hybrid electromagnetic mode, having non-zero Ez and ㎐) are analyzed in detail using non-decaying mode method. The mode charts are completed. The validity of the theory is confirmed by experiments. The results were on the whole satisfactory. Experimental measurements show excellent agrement with the numerical results. The average error of TE, TM, and HEM mode is about 0.20 %, 0.14 %, and 0.28 %, respectively.
